IMPROVEMENT IN PORTABLE FIELD-HARROW.

'l'he Schedule referred to in these Letters Patent and making part cftho lame.

To all whom it may come/rn:

Be it known that I, JACOB D. JOHNSON, of Tylersville, in the county ofClinton, and State of Pennsylvania, have invented a new and usefulPortable Field- Harrow, consisting of a barrow and sled combined; and Ido hereby declare that the following is a full and exact descriptionthereof, reference being had to the accompanying drawings, and to thelettersof ref-l B, the arms, the outer ends of whichit binds. These armsmeet in the centre of the barrow, and are held together'by means of themetal plates, or

clamps C, to'which they are bolted.

The lower sides of the arms B are provided with a suitable number ofbarrow-pins.

The cross-beams, D and D', and their braces, and

E', form the frame of the sled, and F F are its runners.

The sled is inverted, and placed on top ofthe harrow, and is attachedthereto by means of the bolt G, which runs through the barrow-framewhere the beams D and D' intersect each other, and through the centre ofthe metal plates, or clamps C, as shown in iig. 1, and is held there bythe pin h, running through an eye in its end.

frame, projects beyond the metal band, or tire, and forms the handle H,by means of which the driver can raise the barrow from behind whennecessary.

The short end of this beam and the ends of the braces E and E aremortised together, and are bound with the clevis-shaped metal plate I,to which the Working-team is hitched.

The sled-frame tends to keep the barrow steady While in motion, and thelong `end of the beam D prevents the straining of the bolt G.

The harrow can be readily moved from place -to place by turning it overon its runners.

What I claim as my invention, and desire to secure by Letters Patent,is-

A portable field-barrow, consisting of a rotary harrow and sled,constructed, arranged, and combined in the manner shown, and for thepurposes herein set forth and described.

have hereunto set my hand, this 30th day of September, 1868. v
